Abstract
The utility model discloses a gas probing device with a telescopic rod. The gas probing device comprises a telescopic device, a front device, a universal connector between the telescopic device and the front device, and a gas sensor mounted in the front device, wherein the gas sensor is the sulfur hexafluoride and oxygen content double-gas sensor. The gas probing device disclosed by the utility model is provided with the telescopic rod to adjust the length of the device so as to achieve the portable performance of the device; the gas sensor can be convenient to place at any area required to detect the gas; the flexibility and detection range of the gas sensor can be improved; the gas is convenient and fast to detect; the operator can detect the gas detection result in the safe area on real time; the operator is not necessary to enter the danger detection area, so that the personal safety of the operator can be ensured.
Description
Technical field
The present invention relates to a kind of gas detection apparatus, be specifically related to a kind of gas detection apparatus with expansion link.
Background technology
At present, the sniffer of the gas of prior art includes removable gas detecting and alarming instrument.With component-assembled such as sensor, metering circuit, display, alarm, rechargeable batteries in a housing, the formula that becomes one instrument, small volume and less weight is easy to carry.The shortcoming of this kind detector is; When detecting harmful gas, the staff carries this detector and gets in the zone that is scattered with harmful gas and detect, and harmful gas might cause danger to staff's personal safety; Lack safe distance; As have length apart from rod-like device, it is convenient not to the utmost to carry, hard transportation.
Summary of the invention
The purpose of this invention is to provide a kind of being convenient for carrying, but possess again when detecting safe distance gas detection apparatus.
In order to achieve the above object; The present invention provides a kind of gas detection apparatus with expansion link; This device comprises expansion link, front device, the joint coupling between expansion link and front device; Be arranged on the gas sensor in the said front device, gas sensor adopts sulfur hexafluoride and oxygen level double gas sensors.
The gas detection apparatus of above-mentioned band expansion link is characterized in that, described expansion link; Also comprise 2-4 and save hollow shaft; Fixture splice is fixed on an end of shaft through screw thread, and O type rubber ring is placed in the fixture splice, connects upper level shaft and next stage shaft;
The gas detection apparatus of above-mentioned band expansion link is characterized in that described gas sensing comprises alarm control circuit.
Expansion link is 1 joint when carrying device sets out, and when the relevant scene of arrival was tested, the stretching shaft was stretched to necessary distance.
Gas sensor is surveyed the gas at gas detection point place, provides sound and light alarm information to operating personnel through being electrically connected the gas detection data that make alarm control circuit receiver gases sensor detection data.Wherein be lower than or sulfur hexafluoride content concn when exceeding standard when oxygen content, gas sensor promptly sends alerting signal, reports to the police to operating personnel.
The gas detection apparatus of band draw-tube of the present invention is compared with the gas detection apparatus of prior art, and its advantage is that the present invention is provided with expansion link and joint coupling; Carry gas sensor; Can easily gas sensor be arranged to the zone that any needs carry out gas detection, improve the flexibility ratio and the sensing range of gas sensor, can carry out gas detection easily; And be easy to carry convenient transportation;
The expansion link that the present invention is provided with; Operating personnel can be through the result of receiver gases sensor to gas detection in the safety zone of far-end; Operating personnel can be detected the gas detection result in the safety zone in real time; Stopped operating personnel and must get into necessity, guaranteed operating personnel's personal safety with dangerous surveyed area.
Description of drawings
Fig. 1 is the structural representation of the gas detection apparatus expansion link of band retractor device of the present invention;
Fig. 2 is the gas detection apparatus structural drawing of band retractor device of the present invention.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present invention is described.
As shown in Figure 1, the present invention has explained a kind of gas detection apparatus with expansion link, comprises retractor device 1, front device 2, and the joint coupling 3 that retractor device 1 and front device are 2 is arranged on the gas sensor 4 in the front device.
Wherein gas sensor 4 adopts sulfur hexafluoride and oxygen level double gas sensors.It comprises oxygen level sensor and sulfur hexafluoride sensor; Oxygen level sensor adopts Japan or German imported product, and can arrive 5 years serviceable life, and investigative range is between 14%～26%; When oxygen content is lower than 18.6%, send alerting signal, can satisfy the requirement of this device.
The operation workflow of the gas detection apparatus of band retractor device of the present invention is described below in conjunction with Fig. 1, Fig. 2.
Carry monitoring device to the zone that needs monitoring by operating personnel, when carrying, manually shrink retractor device 1; Contracted to 1 joint by the 2-4 joint, O type rubber ring 13 ensures associative operation through friction force, arrives to survey the place; Again 1 joint is stretched to the 2-4 joint; According to the monitoring needs gas-monitoring point is monitored, detect index of correlation like gas sensor 4 and exceed standard, send warning through warning circuit.
Although content of the present invention has been done detailed introduction through above-mentioned preferred embodiment, will be appreciated that above-mentioned description should not be considered to limitation of the present invention.After those skilled in the art have read foregoing, for multiple modification of the present invention with to substitute all will be conspicuous.Therefore, protection scope of the present invention should be limited appended claim.
